Sen. Mary Landrieu (D-La.) found that over $33,700 in
campaign flights were inappropriately charged to her official account in
an internal review of her finances released Friday.
The report is sure to draw added scrutiny to her use of charter
planes just as her main opponent, Rep. Bill Cassidy (R-La.), is set to
introduce a resolution meant to highlight such spending, which he calls a
“waste of Americans’ hard-earned tax dollars.”
The review, which was released four days after her self-imposed
deadline of Sept. 8, found that the senator took 43 trips, which
amounted to 136 campaign functions, that were paid for by funds meant
for official business only. Eleven percent of the total amount
Landrieu’s office paid for chartered flights should have been paid out
of her campaign funds, the review found.
Landrieu’s office said she fully reimbursed the Treasury with
campaign funds and has notified the Senate Ethics Committee of the
errors. She also said in a statement that she’s implemented a new
bookkeeping system to prevent similar errors from happening again.[...]
